Title: Improvements in and relating to automatic adjusting devices for disc brakes
Inventor: ENOCK ROBERT WILLIAM BERNARD
IPC: F16D65/14
Filed: 1964-11-12
Abstract: 1,069,135. Disc brakes. AUTOMOTIVE PRODUCTS CO. Ltd. Sept. 15, 1965 [Nov. 12, 1964], No. 46141/64. Heading F2E. In an automatic wear adjusting device for a disc brake of the kind comprising an internally threaded sleeve arranged within an hydraulic actuating cylinder 3 and threadedly engaging a rod 10 secured to pad-applying piston 4, the sleeve is engaged by the inner end 8 of a push rod 5 which is movable axially within a sealed bore in the end wall of the cylinder by manual applying means 24-27, and there is associated with the sleeve pawl and ratchet mechanism for automatically increasing .the length of the assembly. For this purpose the sleeve carries a ratchet wheel 11 which is engaged by a toothed ring 14 (which may, as shown, have only four teeth) rotatable about the sleeve, such rotation being effected by a pawl 18 which is pivoted at 19 to the end 8 of the push rod and has a rounded end 17 engaged in a slot cut in the periphery of the ring 14. The pawl also has a laterally extending portion including an abutment 22 which is engaged by one end 21 of a leaf spring to retain this portion normally in contact with the cylinder rear wall, the other end 23 of the leaf spring being arranged to restrain rotation of the sleeve, so that, in operation, axial movement of the push rod 5 by the manual applying means causes the pawl to pivot and rotate the ring 14. If wear is excessive the ring 14 engages a fresh set of teeth on the ratchet wheel 11, so that on subsequent release of the brake adjustment is effected. A light spring 15 maintains the ring 14 in engagement with ratchet wheel 11. The effect of the spring 15 may be overcome, so far as release of the associated brake pad or pads is concerned, by a washertype spring (31) (Fig. 2, not shown) inserted between the outer face of the cylinder rear wall and a flange formed on a retaining cap 29 for the member 27 of the applying means. In fluid-pressure application of the brake the push rod 5 remains stationary in either case, so that no adjustment is effected.

Title: Improvements in and relating to gas or vapour detectors
Inventor: GREGORY NORMAN LENNOX
IPC: G01N27/64
Filed: 1962-12-06
Abstract: 1,070,741. lonization chambers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 14, 1964 [Dec. 6, 1962], No. 46167/62. Heading H1D. Gas or vapour analysis apparatus is so constructed that the gas or vapour mixture undergoing analysis is prevented from contacting an internal ionizing means. As shown, an insulating body 2, e.g. of P.T.F.E., and a conductive body 3, e.g. of brass, are separated by an apertured cathode 4 and insulator 5 to form a detecting chamber 8 and a chamber 11 for an ionizing means of sodium 226 sandwiched between gold or silver foils formed into a cylinder 12. An inert gas such as nitrogen introduced through a pipe 13 provides a flow through the orifice 6 thus preventing the mixture for analysis, which is introduced through a pipe 10, from entering the. chamber 11. A pipe 14 provides an outlet for all the gases. The presence of various components in the gas mixture is indicated by changes in the electron current between the cathode 4 and an anode 7 which is supported in the chamber 8 by a plug 9. The detector may be operated either as an electron-capture type or as an electron mobility type. Alternatively, a recessed conductive insert may replace the plug 9 to provide an argon detector (Fig. 2, not shown).

Title: Oil tankers
IPC: B63B57/00
Filed: 1970-09-29
Abstract: 1379540 Ejecting imflamible gases from tanks SWAN HUNTER GROUP Ltd 6 Dec 1971 [29 Sept 1970] 46196/70 Heading A5A A method of flushing out a hydrocarbonrich atmosphere from an oil tank to obviate the risk of explosion consists in introducing into the tank a water/surfactant foam and allowing this foam to build up from the bottom of the tank and to eject in front of it the atmosphere in the tank. The foam may be introduced by a cylindrical chute extending from the top to the bottom of the tank, the chute having orifices at different levels above its lower end from which the foam can escape. Alternatively the foam may be introduced through ducts, at least one of which leads into the tank through the wall of the tank near the bottom of the tank. The specification also claims an oil tanker ship having a foamforming apparatus, ducts capable of passing foam to respective oil storage tanks, inlets on the ducts capable of being coupled to the foam-forming apparatus, and means for introducing foam from the ducts to the tank bottoms to build up progressively therefrom. The said means may include a chute or guide attachable to a duct outlet remote from the tank bottom, or an outlet adjacent the tank bottom from a duct leading through the tank wall near the bottom. The ducts may have a butterfly or other valve therein and the inlets to the ducts may be accessible at deck level, for example taking the form of cowls. Suitable foam-forming apparatus is described in Specification 1238761. The foam forming composition may be a 1-3% by wt. solution of lauryl sulphate or lauryl ether sulphate in fresh or sea water, containing a foam stabiliser.

Title: Improvements in the ethoxylation of amines and their derivatives
IPC: C07C217/50
Filed: 1968-10-02
Abstract: 1,245,420. Ethoxylation of amines. HENKEL & CIE G.m.b.H. 2 Oct., 1968 [4 Oct., 1967], No. 46668/68. Heading C2C. Ethoxylated amines are produced by a continuous method by passing a reaction mixture comprising ethylene oxide and a primary or secondary amine, or its addition product with ethylene oxide, propylene oxide or butylene oxide, in a molar ratio of from 1:1 to 6:1, optionally together with a catalyst for the addition reaction, through an elongated reaction zone surrounded by a heat exchanger, controlling the temperature of the reaction mixture such that in the first half of the zone the reaction mixture attains a temperature of at most 240 C. and in the remainder of the zone attains a maximum temperature of 250-360 C., the proportion of the total reaction time in the reaction zone remaining after attainment of the maximum temperature being 5-30% of the total time in said zone and the time spent in the zone is 10-150 seconds, the pressure being such that the reaction mixture remains in liquid form, and cooling the reaction mixture to a temperature below 150 C. immediately after leaving the reaction zone. The pressure applied is preferably 50-100 atmospheres and the catalyst may be caustic soda, caustic potash, alkali metal alcoholate or metallic Na or K. In the examples, n-dodecylamine, C 8-18  coconut amine, n-hexylamine, erucylamine and cyclohexylamine are ethoxylated.

Title: Improvements in fluidic temperature sensor system
IPC: F15C1/00
Filed: 1969-09-24
Abstract: 1,268,453. Acoustic thermometer. GENERAL ELECTRIC CO. 24 Sept., 1969 [17 Oct., 1968], No. 46911/69. Heading H4D. In a system for sensing the temperature T of a region by detecting the phase shift # of a fluid pressure wave signal in being transmitted through a sensor tube disposed in a medium in the region, fluidic devices are used for the signal generation and phase shift detection and the fluid in the tube is isolated from the medium to avoid contamination by the medium. In the Fig. 1 embodiment fluidic oscillator 15 and amplifier 16 superimpose an oscillatory component on the steady pressure provided by source 12 for the fluid (e.g. air or water) in sensor tube 10. Tube 11 acts as a pre-heater for the fluid. The single-ended pressure signal at the output 18 of tube 10 is converted to a pushpull signal at the output of amplifier 22 by passing it to the control jets of amplifier 22 via resistance 25 and a low-pass filter (resistance 26 plus capacitance 27) respectively. The phase shift detector, 17, comprises rectifiers 20, 21 each receiving at its control jets the input pressure signal of tube 10 and the push-pull signal from one receiver of amplifier 22. Low-pass filters 23, 24 smooth the rectifier outputs to give a differential output pressure #P o  dependent on the phase shift. The rectifiers are such that #P o  has a null for # = n#/2 (n = 1, 3, 5 ...) and the sensor tube length and oscillator frequency are selected such that there is a null at some reference temperature, i.e. their selection determines n. #P o  then represents the deviation of T from the reference temperature. By selecting a high value of n, the apparatus sensitivity d#/dT is increased, but at the expense of useful temperature range (since # must be less than 180 degrees to avoid ambiguity). To overcome this a dual-mode system, Fig. 7, is arranged to operate normally at high-n but to switch to low-n operation if the temperature deviation exceeds a predetermined limit. The high-n operation is provided by oscillator 15b and phase shift detector 17b, the low-n operation by oscillator 15a and phase shift detector 17a. Amplifier 70 or 74 is enabled to pass an output to summing amplifier 73 according to the state of a switch 76 which compares detector 17a output with a threshold set by a pressure P B  and switches on amplifier 70 only when the threshold is exceeded, i.e. when there is a large temperature deviation. In alternative dual-mode systems (a) the low-n mode is provided by a Helmholtz oscillator whose frequency is a function of the sensed temperature and this frequency is compared with a fixed high-n mode frequency to determine if the temperature deviation exceeds the predetermined limit (Fig. 8, not shown) or (b) a single oscillator is used to excite two sensor tubes of different length (not shown).
